BRUSH HEIGHT ADJUSTMENT
IMPORTANT: If brush height is set too low,
brush can drive machine rearward when
attachment clutch is engaged. Engage brush
slowly with brush set at proper height.
Adjust caster wheels to the hole nearest 1/8-
1/4 inch (3-6 mm) above surface. For hard
surfaces, adjust the caster wheels so that
brush just touches surface. The brush works
best with the brush properly leveled. To adjust
the brush height:
1. Move the brush to a dusty, flat surface.
Leave the engine running.
2. Start the brush at a slow speed. Run the
brush in a stationary position for 30
seconds.
3. Lift the brush head assembly off the
ground and reverse the unit to move it
away from the swept area.
4. Stop engine and allow all moving parts to
stop.
5. Check the width of the swept area. The
brush pattern should be 2-3 inches (5.08-
7.6 cm) wide, running the length of the
brush. (See Figure 6).
6. To adjust, remove the caster wheel
support pins (one each side). Slide caster
wheel supports up or down as required.
Align the holes in the outer sleeve with
the holes in the wheel supports.
